Best Solar Power Banks for Emergencies
When it comes to backup power for your smart devices solar power banks are definitely an option you want to consider. Not only can they provide emergency power for your devices during a power outage but they can recharge themselves using built in photovoltaic cells.
Solar power banks are most often thought of as being for outdoor activities like camping and hiking but they should be considered an essential part of your Safety Preparations. For this reason size is important, you don’t want a cloudy day preventing you from having the power you need to keep safe.
A solar-powered Backup Power Supply is an excellent way to make sure you have the power you need when the time comes. Unfortunately Most of the
small Solar Power Banks sold are inadequate for use as a longer term emergency power supply. Even the ones with larger capacity batteries may struggle to recharge themselves fast enough to be of any help with only the single solar cell on one side.
A single solar cell on a typical handheld solar power bank ranges from around 1.5 to 3 Watts while a typical USB wall charger ranges from 9 to 16 Watts. This means the amount of time necessary to recharge the power bank’s batteries with the one solar cell will be longer than the amount of time it takes to discharge your device. This means at some point you’re going to have both a dead power bank and a dead device and be unable to use one or both uninterrupted for hours and possibly days.
For your consideration we have assembled a list of Amazon’s best selling and Highest Rated Solar Power Banks with the solar capacity to keep your cell phone charged for a extended amount of time, depending on the conditions you’re using them in of course. If you have multiple devices you should consider purchasing multiple solar power banks, one for each device.
